WORCESTER — A local lawyer has been charged with assaulting a nurse and a police officer in separate incidents while a patient at the UMass Memorial Medical Center — University Campus.

Albert G. Hayeck, 53, of 6 Lapierre St., was arraigned Wednesday in Central District Court on charges of assault and battery on a health care professional, assault and battery on a police officer, threatening to commit a crime (murder), resisting arrest and disorderly conduct.

Mr. Hayeck was released on personal recognizance by Judge David B. Locke, who entered not-guilty pleas on his behalf and continued his case to Aug. 13.

On April 12, two UMass Memorial Medical Center police officers were called upon to assist medical staff in the intensive care unit in their efforts to restrain Mr. Hayeck, who allegedly struck a nurse during the struggle, according to court documents. Later that day, Mr. Hayeck allegedly threatened to return to the hospital with a firearm.

On June 8, a UMass officer was asked by nursing staff to check on the status of a patient, later identified as Mr. Hayeck, who was leaving the emergency room in the direction of the lobby, according to court records. When the officer approached to verify Mr. Hayeck's discharge, Mr. Hayeck allegedly became loud and "aggressive" and struck the officer in the throat with a closed fist.

He is also accused of resisting the officer's efforts to place him in handcuffs after he had been told he was under arrest.

Lawyer Michael C. Wilcox, who represented Mr. Hayeck at the arraignment, told Judge Locke his client has been under the hospital's care.

As conditions of his release, Mr. Hayeck was ordered to have no contact with the alleged victims, to surrender any firearm, license to carry a firearm or firearm identification card he possesses and to give UMass police 24 hours' notice if he has a scheduled appointment at the hospital.
